Definitions
- the present invention relates to cleaning devices for a threaded shaft.
- threaded screws or shafts have been used to linearly translate the position of a threaded member, such as a threaded block engaged with the threads of a shaft, in opposite directions depending upon the direction of rotation of the shaft, such as in a printing press.
- a threaded member such as a threaded block engaged with the threads of a shaft
- dust and dirt may accumulate in the threads of the shaft, which hampers movement of the threaded shaft, and possibly jams the shaft such that it can no longer rotate in the block.
- the device must be stopped in this case, and the threads of the shaft must be cleaned prior to subsequent use, causing undesirable delays and inconvenience to the operator of the press or device.
- a principal feature of the present invention is the provision of an improved cleaning device for a threaded shaft.
- the cleaning device of the present invention comprises, a cleaning member having a threaded recess received on a threaded shaft and extending partially around the shaft, with the threads of the cleaning member meshing with the threads of the shaft.
- a feature of the invention is that the cleaning member scrapes the threads of the shaft during rotation of the shaft.
- Another feature of the invention is that the scraping by the member removes dirt and dust from the threads of the shaft.
- the cleaning member has a shape to provide a scraping or cleaning edge contacting the shaft as it rotates in a direction towards the scraping edge.
- the cleaning member may have a pair of spaced cleaning edges for scraping and removing the dust and dirt from the shaft during rotation of the shaft in opposite directions.
- a further feature of the invention is that the cleaning device may comprise a pair of cleaning members, with each of the cleaning members scraping the threads of the shaft in opposite rotational directions of the shaft.
- Yet another feature of the invention is that the cleaning device is of simplified structure and reduced cost.
- a further feature of the invention is that the cleaning member may be easily placed and removed relative to the threaded shaft.
- the cleaning member may be snap-fit onto the threaded shaft.

- the cleaning member 34 may be snap-fit on the threaded shaft 12 into a configuration with the threads 44 of the cleaning member 34 meshing with the threads 14 of the shaft 12.
- the cleaning member 34 is secured at a fixed position on the threaded shaft 12 through use of the bolt 38 extending through the cleaning member 34 into the block 20, or other suitable mounting device.
- the cleaning member 34 has a generally planar first side surface 46 facing the block 20 when the cleaning member 34 is secured to the block 20.
- the cleaning member 34 also has a second generally planar opposed second side surface 48 which is disposed at an angle relative to the first side surface 46 of the cleaning member 34, such that the angle must be equal to or greater than the thread angle.
- the cleaning member 34 has an inner face 50 defining a first edge 52 of the threads 44 of the cleaning member 34 adjacent the threaded recess 42, and a second opposed edge 54 of the threads 44 adjacent the recess 42 of the cleaning member 34. In this configuration, the second edge 54 of the cleaning member 34 has a greater length of the threads 44 adjacent the second side surface 48 of the cleaning member 34 than the first edge 52 of the cleaning member 34.
- the edge 54 of the cleaning member 34 has threads 44 being directed in the edge 54 in an opposite angular direction relative to one direction of rotation of the threaded shaft 12.
- the edge 54 of the cleaning member 34 first contacts the threads 14 of the threaded shaft 12 prior to the threads 44 of the first opposed edge 52, such that the threads 44 in the second edge 54 scrape the threads 14 of the shaft 12, and remove dirt and dust which may accumulate on the threads 14 of the shaft 12.
- the cleaning member 34 forms a scraping edge of the threads 44 in order to remove dirt and dust from the threads 14 of the shaft 12 in one rotational direction of the shaft 12.
